A method of manufacturing an electro- tin plating solution and ceramic electronic components

摘要

PROBLEM TO BE SOLVED: To provide an electrolytic tin plating solution that controls corrosion of a ceramic electronic component body, which is caused by plating, and achieves stable plating, and to provide a method for manufacturing a ceramic electronic component using the electrolytic tin plating solution.;SOLUTION: The electrolytic tin plating solution for the ceramic electronic component contains stannous ion and a chelating agent, and whose pH is controlled between 6-9, and whose value of the relation (molar concentration of the chelate agent)/(molar concentration of stannous ion) is controlled higher than 2.4 and 4.5 or less.;COPYRIGHT: (C)2012,JPO&INPIT
